Remote Authentication Dial-In User Service (RADIUS) Usage for
Simple Network Management Protocol (SNMP) Transport Models
Abstract
This memo describes the use of a Remote Authentication Dial-In User
Service (RADIUS) authentication and authorization service with Simple
Network Management Protocol (SNMP) secure Transport Models to
authenticate users and authorize creation of secure transport
sessions. While the recommendations of this memo are generally
applicable to a broad class of SNMP Transport Models, the examples
focus on the Secure Shell (SSH) Transport Model.

This memo describes the use of a Remote Authentication Dial-In User
Service (RADIUS) authentication and authorization service by Simple
Network Management Protocol (SNMP) secure Transport Models to
authenticate users and authorize creation of secure transport
sessions. While the recommendations of this memo are generally
applicable to a broad class of SNMP Transport Models, the examples
focus on the Secure Shell Transport Model.
In the context of this document, a Network Access Server (NAS) is a
network device or host that contains an SNMP engine implementation,
utilizing SNMP Transport Models. It is customary in SNMP documents
to indicate which subsystem performs specific processing tasks. In
this document, we leave such decisions to the implementer, as is
